SWINE 369 



Wheat. — Wheat is on a par with corn as a feed for hogs. The 

 price of wheat nsually makes it iirohibitive for feeding purposes. 



Barley. — Bark^y ranks next to corn and wheat as a fattening 

 feed for hogs. Palatal)le protein feeds shoiikl be fed with barley. 



Middlings. — Middlings are one of the popular feeds for pigs. 

 They contain more protein and less carbohydrates than corn. 

 They contain little bone-building material and should always be 

 fed witli corn, tankage, etc. 



Tankage. — Tankage is a waste product of packing plants. It 

 consists of meat scraps, fat trimmings and scrap bones thor- 

 oughly cooked, sterilized and ground. Tankage usually carries 

 from forty to sixty per cent of digestible protein, together with 

 considerable fat and ash. It is universally used as a supplement 

 witli corn and other carbohydrate feeds. 



Milk. — Skim milk and buttermilk rank as the best supple- 

 ments to use with fattening feeds. In addition to their protein 

 content, they furnish growth accessories or vitamines M'hich are 

 necessary for normal growth. Both are profitably fed in the 

 proportion of three pounds of milk to one jDOund of grain. 



Garbage. — A limited amount of garbage can be fed with good 

 results. Where garbage makes up the bulk of the feed, great 

 care must be taken in feeding unless ''garbage-bred" stock is 

 used. 



Forage crops. — Forage crops are indispensable for the proper 

 feeding of swine. They furnish the necessary bulk and succu- 

 lence to the ration. They also supplement the starchy feeds and 

 supply the much-needed growth accessories. The legumes are 

 especially good as they supply not only protein but also bone- 

 building material. Various tests have demonstrated that the 

 forage crops rank about as follows : Alfalfa, red clover, dwarf 

 Essex rape, soy beans, and blue grass. 



As a rule when feeding swine : 



1 bushel corn fed alone returns 10 pounds gain. 



1 bushel corn fed with pasture returns 14-17 pounds gain. 



1 bushel corn fed with tankage returns 17 pounds gain. 



1 bushel corn fed with skim milk returns 22 pounds gain. 



Stock foods. — Experimental evidence obtained by several 

 experiment stations has proven that the use of condimental stock 

 foods with hogs, did not result in either larger or cheaper gains.
